When data is normally distributed with no outliers, then the mean and median can both be used to represent the true center of the data. Introduction to Measurement. We would rather deal with the units we started with (points in this case), so to convert back we take the square root and get: Population standard deviation=\(\sqrt{\dfrac{50}{10}}=\sqrt{5} \approx 2.2\), sample standard deviation=\(\sqrt{\dfrac{50}{9}} \approx 2.4\).
